"I never expected that I would comprehend the Unity of Heaven and Man while still a Demon General!" Xiao Long thought to himself.

The Unity of Heaven and Man signifies a perfect harmony between the physical body and nature, allowing one to effortlessly manipulate the Spiritual Qi of the world for personal use.

Most people only achieve this state at the Sovereign Realm, forcibly aligning with the natural mysteries to reach the Unity of Heaven and Man.

There are also a very few Demon Beasts with special constitutions, naturally born into the Unity of Heaven and Man, such as Xiao Bai. However, Xiao Bai possesses the Immortal Spirit Body, which is even more powerful than the Unity of Heaven and Man.
